Stocks were indicated marginally higher on Friday despite a weak growth reading on gross domestic product, but this is on the heels of a very strong week for the last trading day of April. This bull market has now raged on more than eight years and investors have found myriad reasons to buy every single market sell-off for more than five years now. Those same investors are also still looking for new trading and investing ideas.

24/7 Wall St. reviews dozens of analyst research reports each day of the week in an effort to find new ideas for our readers. Some analyst reports cover stocks to buy and others cover stocks to sell or to avoid. Some color has been added on many of the following calls, and references to consensus analyst price targets are from Thomson Reuters.

These were the top analyst upgrades, downgrades and other research calls on Friday, April 28, 2017.

Alphabet Inc. (NASDAQ: GOOGL) was last seen trading up over 4% at $929.00 at new highs after beating earnings. Jefferies reiterated its Buy rating and raised its target to $1,200 from $1,000.

Amazon.com Inc. (NASDAQ: AMZN) was last seen trading up 3% at $946.00 at a new high after earnings. Wedbush maintained its Outperform rating and $1,250 price target.

Nabors Industries Ltd. (NYSE: NBR) was down 10.2% at $10.55 on Thursday on more than four times normal trading volume after reporting a loss. Nabors was maintained as Buy at Goldman Sachs with a $17.50 price target, but the firm removed it from the prized Conviction Buy list.

United States Steel Corp. (NYSE: X) was slammed this week and already saw multiple analyst downgrades. On Friday morning, Macquarie joined the downgrade brigade and cut U.S. Steel’s rating to Underperform from Neutral.

Western Digital Corp. (NASDAQ: WDC) was last seen trading up over 8% at $92.32 after earnings, missing the Seagate reaction. Western Digital was downgraded to Market Perform from Outperform at Wells Fargo, but it was raised to Buy from Neutral at Merrill Lynch. It was raised to Overweight from Equal Weight with a $120 price target at Morgan Stanley. Cowen has an Outperform rating and raised its target to $115 from $90.

As this the last trading day of April, 24/7 Wall St. has come up with eight defensive stocks for investors to hide out in if they are fearful of a coming market correction. After all, there is always the “sell in May and go away” mantra, and then there is the worry that the summer doldrums will come into play.
