The holidays have come early for a couple of this year's most-watched technology companies. I'm talking about Palantir Technologies (NASDAQ: PLTR) and MicroStrategy (NASDAQ: MSTR), software players that have soared more than 300% and 500%,

Palantir, which is preparing to join the Nasdaq 100, is down Monday. Palantir stock shed more than 4% to 72.67 in midday trade after Nasdaq Inc. said the shares will be added to the Nasdaq 100 before the market opens Dec.

Investors are snapping up the three stocks that are set to join the Nasdaq 100 next week, judging by premarket action.
