Wall Street investment portfolios are starting to look similar.

Bernstein analyst Ann Larson showcased this phenomenon last month, showing that Visa, Microsoft, and Amazon were some of the most crowded trades, tracking institutional ownership, long-term momentum, earnings forecasts and valuations.

Tesla, which disappointed investors last week with a surprise miss in earnings, is also on the list.

Here's a list of the top 10 most crowded companies.
