Merlin’s October buys versus Colonial’s 50% discount

Colonial’s discount sets the frame, Merlin has to answer it

Madrid and Barcelona property names are not trading in a vacuum. Spanish real estate investment reached nearly EUR 15 billion through September 2026, up 35% year over year, and that has kept the listed socimi complex in play even as financing costs have stayed awkward. Merlin Properties, Merlin Properties, Socimi, S.A., sits right in the middle of that tension. It has scale, it has a data-center angle that brokers keep circling, and it has a stock price that has already done a lot of the work for you.

Colonial is the cleaner peer for the valuation side of the comparison. The office-focused name is trading at a steep discount to net tangible assets, around 48% to 50%, which is the sort of gap that can make even a mediocre asset base look interesting if rates stop biting. Merlin is not the same animal. Its pitch is less about a static discount and more about whether the market will pay up for a portfolio that analysts expect to shift toward data centers over time. That is where the insider buying matters. It lands after a sharp reset in the share price, not after a euphoric run.

Two October buys, one stock that had already been marked down

The filings themselves are straightforward. Fernando Ferrero Cantan bought about EUR 11,410, euro-normalised filing value, and Fernando Ramírez Baeza bought about EUR 21,127. Both transactions were dated 15 October and reported on 18 October. Both were buys. Both were tagged as cluster activity in our data. The amounts are small in absolute terms, but that is not the point here. On a company with a market value of EUR 7.22 billion, these are not balance-sheet moves. They are personal buys by operating directors into a stock that had already been cut down.

The price context matters because it changes the meaning of the filing. Merlin closed near EUR 11.5 to EUR 11.7 in mid-October trading, down roughly 28% from June 2026 highs near EUR 16. That is a real drawdown, not a cosmetic wobble. You do not need to dress it up. When a director buys after a move like that, the market is forced to ask whether the stock has simply become cheaper or whether the business case has improved enough to justify the risk. The answer is not obvious, which is why the filing is useful.

Merlin’s data-center story versus Colonial’s discount story

Colonial gives you the old-school REIT argument in its purest form. The shares trade at a deep discount to asset value, and the market is effectively saying the portfolio is worth less than the accounting says it is. That can be a setup for rerating if rates ease or if investors decide the discount is too wide. It can also stay wide for a long time. The discount itself is not a catalyst.

Merlin’s case is different. Analysts have been leaning on the data-center portfolio as the growth engine, with Morningstar noting an expected rise from a low single-digit share of gross rental income to around 65% by 2032. That is the kind of shift that can change how the market values a property company. It also introduces execution risk. You are not just underwriting a portfolio of offices, logistics and retail. You are underwriting a transition into a more infrastructure-like asset mix, with all the capex, leasing and financing questions that come with it.

That is why the comparison with Colonial is useful. Colonial is the valuation trade. Merlin is the transition trade. If you want a simple discount, Colonial is the cleaner expression. If you want a company where the next few years could change the mix of earnings and asset quality, Merlin is the more interesting one. The insider buying does not settle that debate. It tells you which side of the argument some directors are willing to back with cash.

Rates are still the problem, and Merlin is not immune

The macro backdrop is still hostile enough to keep real estate investors honest. The European Central Bank raised its deposit rate by 25 basis points in September to 2.50% amid an energy-price shock tied to geopolitical tensions in the Middle East, with headline inflation recently near 3.8%. Markets and polls have also pointed to the possibility of another hike in December. That combination has pushed financing conditions tighter and long-term yields higher, which is exactly the sort of environment that compresses property valuations and makes refinancing less forgiving.

For Merlin, that matters more than for a lot of sectors because the stock is being asked to do two things at once. It has to absorb the rate pressure that hits every listed property name, and it has to convince the market that the data-center strategy deserves a premium rather than a discount. Colonial has the same rate headwind, but its valuation case is more static. Merlin’s is more exposed to timing. If the market keeps punishing duration, the rerating story gets delayed. If rates stabilize, the market can start to separate the better assets from the rest.

The recent analyst tone has been constructive, but not blindly so. Jefferies upgraded Merlin to Buy with a EUR 16.00 target on 14 October. Goldman Sachs followed with a Buy and a EUR 17.70 target on 15 October, calling Merlin a preferred data-center play. Bernstein kept a Buy but trimmed its target to EUR 16.80 from EUR 18.80 around the same period. That is a useful spread of opinion. Nobody is treating the stock as broken. Nobody is pretending the path is clean either.

What the cluster says when you put it beside Colonial

Insiders Trades data scores the Merlin buys at 38, and the reason is not mysterious. The filings came from an operating director, they sit inside a wide cluster, and the amounts are tiny relative to the company. Our data shows seven insiders trading the name in the same direction over the past quarter, which is the configuration our scoring rewards most. That is the part that makes the October buys more interesting than a lone nibble from a random director. The cluster says the buying is not isolated.

The comparison with Colonial sharpens the point. Colonial’s discount is public and visible. Anyone can see the gap to net tangible assets and decide whether it is wide enough to matter. Merlin’s insider pattern is less visible and more behavioral. It does not tell you the stock is cheap in the same mechanical way. It tells you that several insiders have been willing to buy while the shares are still well below the June highs and while the market is still debating the data-center transition. That is a different kind of evidence.

The historical cohort data is worth one clean read and then you move on. In the director-level buys at large-cap names bucket, the 90-day win rate is 56.4% and the average 90-day return is 4.42%, with a 365-day average return of 86.49%. That is historical cohort data, not a forecast for Merlin and not a promise that this trade will work. It simply says that, in this role-and-size bucket, the follow-through has been positive more often than not. Useful. Not magical.

The stock has already done some of the work for the bulls

Merlin’s share price reset changes the burden of proof. When a stock is still near its highs, insider buying can be read as a confidence flourish. When it is down roughly 28% from June highs near EUR 16, the same action reads more like a response to dislocation. That does not make it right. It makes it more grounded. The market has already marked the name down enough that a director can buy without looking like he is chasing momentum.

Colonial, by contrast, is still being judged through the lens of asset value. The market is asking whether the discount is too wide. Merlin is being judged through the lens of future mix. The market is asking whether the data-center exposure can justify a better multiple once rates stop moving against the sector. Those are related questions, but they are not the same. One is about what the buildings are worth now. The other is about what the portfolio could become.

That distinction matters because it changes how you read the insider activity. A buy at Colonial would mostly speak to valuation discipline. A buy at Merlin speaks to both valuation and strategy. The directors are buying a stock that has been hit, but they are also buying into a story that depends on execution over several years. That is more ambitious, and more fragile.

What would make this comparison fail

The obvious risk is that rates stay higher for longer and the market keeps punishing property duration. If that happens, the discount argument at Colonial can remain a discount argument, and Merlin’s transition story can get stuck in neutral. Higher financing costs would not just pressure sentiment. They would also make every incremental step in the data-center buildout more expensive to fund.

The second risk is that the market decides Merlin’s data-center promise is already in the price. Analysts have been constructive, and that can help, but it can also leave less room for surprise. If the portfolio mix does not shift as expected, or if the economics of that shift are slower than the market wants, the stock can drift back toward being treated like a standard property name. In that case, the insider buys become a footnote rather than a marker.

There is also a simple size issue. The two October purchases are real, but they are not large relative to the company. EUR 11,410 and EUR 21,127 are not the kind of numbers that force a thesis change on their own. They matter because they arrive in a cluster, because they come after a drawdown, and because they line up with a period of active analyst support. Strip away any one of those pieces and the signal gets weaker.

The comparison that matters into the next print

If you are choosing between Merlin and Colonial, you are really choosing between two different ways to express a view on Spanish listed property. Colonial gives you the cleaner discount to asset value. Merlin gives you the cleaner growth narrative, but with more execution risk and more sensitivity to rates. The insider buying does not erase that split. It just tells you where some directors are putting money while the market is still sorting it out.

Insiders Trades data puts the Merlin cluster in a bucket that has historically done fine over 90 days, and the company’s own fundamental profile is not weak. Our internal fundamental score is 62, with a quality score of 57. That is not a screaming screen. It is a workable one. The point is that Merlin is not being bought here because everything is perfect. It is being bought after a reset, in a sector that is still attracting capital, and in a name where the market is trying to decide whether the data-center angle deserves to matter more than the rate backdrop.

Watch the next declarations and the next analyst notes, but keep the comparison anchored. Colonial is the discount. Merlin is the transition. The October buys tell you which side of that trade some insiders prefer right now, and the market will get another chance to answer when the next financing, leasing or portfolio update lands.
