Stocks have hit new highs and the Dow Jones Industrial Average blew through 23,000 this week as easily as a knife cutting through butter. Thursday morning was indicated to be a weak open on some expected profit taking.  While many investors may wonder about a correction, the snapshot for the market’s value a year out may even have Dow 25,100 in the cards.

The trend that has prevailed for more than five years now is that investors keep finding new reasons to buy stocks after every major sell-off. Those same investors are also hunting for new investing and trading ideas to generate gains and income ahead.

24/7 Wall St. reviews dozens of analyst research reports each day of the week in an effort to find new investing and trading ideas for our readers. Some of the top analyst reports cover stocks to buy, while other calls cover stocks to sell or stocks to avoid.

Consensus analyst price target data and valuation metrics are from the Thomson Reuters sell-side research service. Additional color and commentary has been added on most of these daily analyst calls.

These were the top analyst upgrades, downgrades and other research calls from Thursday, October 19, 2017.

Allergan (NYSE: AGN) was downgraded to Neutral from Outperform with a $193 price target (versus a $187.15 close) at Mizuho. Allergan was maintained as Outperform at RBC Capital Markets, but the firm lowered its target to $250 from $277.

American Express Co. (NYSE: AXP) has reported earnings and reported that Ken Chennault will retire as CEO. It was reiterated as Hold but the target was raised to $93 from $85 at Jefferies. Amex was indicated down 1.9% at $90.30 on Thursday, in a 52-week range of $64.75 to $93.35.

Nike Inc. (NYSE: NKE) was downgraded to Neutral from Buy with a $54 price target (versus a $52.30 close) at Goldman Sachs, with the firm noting that Nike is likely to be range-bound while it works through excess inventory and on expectations that it will lower expectations at its investor day later this month.
