Which stock do you expect to make more money / higher quarterly return next quarter.

I would expect either ISRG or GOOG have the higher quarterly return. GooG has a tighter distrubution with the average return being roughly .125, IRSG however has a looser ditrubition but shows better returns in some quarters making it riskier but overall positive. SPOT however, is all over the place. Showing unseen highs, and the lowest lows, which could possibly entice a gambler.
