Would a brokerage recommendation be reliable?

Of the 44 recommendations that derive the current ABR, 37 are Strong Buy and three are Buy. Strong Buy and Buy respectively account for 84.1% and 6.8% of all recommendations.

The ABR suggests buying Nvidia, but making an investment decision solely on the basis of this information might not be a good idea.

The overpriced stock isn't going to continue to draw more money into the stock, and it may be time for the stock to enter a correction, with the risk of a short-term pullback increasing.
