You cannot say that for sure as 100% fact and how can you be so certain that he knew the stock was about to tank? The only thing sure is that Mr. Yee Loy Lam needed some money and it does not necessarily have anything to do with the timing you have suggested as fact. It is like me saying you were 2 minutes late for a meeting because of the eclipse of the sun, but the real truth was you were just late because you had an urgent need to go to the washroom. People will draw their own conclusion, but as far as you know, you had to hurry to get to the washroom as the only fact that you know of.
