Shiao Kwang Edmund Tang

Shiao Kwang Edmund Tang appears in our data through filings on Diodes INC /del/ shares, published by SEC (Form 4). Over a trading history stretching from 31 May 2007 to 10 October 2017, the count stands at 55 filings.

Both buying and selling appear: 10 purchases worth €84k, against 24 sales worth €4.2M. Netting one side against the other leaves €4.1M of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 13 share grants and 8 option exercises. So far in 2017, the count stands at no purchases and 5 sales.

Half of the purchases are above €7,357 and half below. Looking at 10 purchases old enough to measure, the stock rose over the following 90 days in 100% of cases; the median change was +77.3%. Past outcomes like these are no guarantee of what comes next.

The newest entry dates from 10 October 2017: an option exercise of €198k, in Diodes INC /del/. The last purchase on record was published on 2 March 2009, which is 6,460 days ago. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
