You have to factor in the cost of the tools.

And also, just because an employee is producing more code or more reports or more trades or more summaries per day, that doesn't guarantee the company will make more money. If you enabled your market analysts to make twice as many trades per day, you will likely lose money if they actually did that. Because they were already finding the good trades, and now they are also making the not-so-good trades and maybe even the unlikely trades.

And also, in the longer term not being shown in existing studies, you are in an arms race with your competitors. Like advertising, you will be spending a lot of that money in order to counter the spending of your competitors, and you both lose the game of prisoners dilemma, the only winner being the arms dealer selling to both sides.
