Has anyone tried the "Speed Boost" in the stock market yet?

I assume (hesitantly) it lowers the timer so that you may complete more stock trades faster. I think I have read through all 20 plus pages but haven't noticed anyone mention it yet.

I'm new to the game, I find it fairly easy and enjoyable so far (company lvl 7) Thanks for this thread, lots of great tips that have helped me!
