Google's stock just got a lot cheaper

One share of Google's parent company Alphabet is suddenly a lot more affordable for Main Street investors — following a massive stock split that took effect Monday.

Alphabet (GOOGL) split its two classes of shares (GOOG) by a 20-to-1 margin, a move that reduced the price of one share from just over $2,200 on Friday to about $110 on Monday.

The stock split doesn't change Alphabet's market capitalization. The company is still worth nearly $1.5 trillion, making it one of the most valuable firms on the planet.
