Whenever you see or read comments from analysts or economists that work directly on Wall Street, the vast majority say the stock market is going up. These people are from the "Sell Side" of the industry meaning they sell products. So, they have an incentive to say stocks are going up because they make more money when they do.
Recently, with each additional 5% decline in stocks, I kept hearing, "It's time to buy. Stocks are undervalued. Get in now." These are the same people who said the exact same thing in 2007 through 2008. If you followed their advice you would have lost a bunch of money.
Avoid listening to these "Sell Side" sales people and get unbiased advice on where to invest your money.
