CNBC's Jim Cramer said Friday he was more positive on the quarterly earnings reports of technology titans Alphabet, Amazon, Apple and Facebook than the stock moves that followed.

But of all those companies, Cramer said on "Squawk Box" that Google-parent Alphabet turned in the best quarter and its stock is the one he would buy, if he could only purchase one. Shares of the online search giant were up by more than 7% Friday, while the three other companies were lower by at least 3%.
