Stocks are nowhere near that deterministic. When people think others will jump ship, they try to jump first, to lose the least money. When people think others will want buy, they buy first or sell higher, because they can get away with it. There's more games theory than future prediction if you ignore long-term investors, as they make up a microscopic amount of the daily trading and thus the daily prices of stocks.

On the other hand, Symbian has some generally good design assumptions (for example client-server division of almost anything) that are hard for programmers that come from other platforms/just don't care and thus it's architecture is often hacked around, which sadly includes many applications written by Nokia itself.
