Often when stories like this come out, the market does the opposite. It is a very difficult game to guess which way the crooks actually will take it though.
The S&P 500 represents 500 stocks, the Dow represents 30 stocks, the Nasdaq, 100 stocks, the Russel, 2000 stocks - and because the Russell represents 2000 stocks, it represents a much broader market, it is generally a much, much better gauge of the markets overall and most often the other markets follow it's direction, this makes the Russell a type of leading indicator.
Since the article was published till now, the markets have not really moved a whole lot.
So just for fun for future reference, as of the close on 09/10/2018, which is about 3 weeks after the article was published, here are the closing numbers to see which way it actually ends up going, just to check the accuracy of the article's "sell signal":
S&P 2877
Dow 25857
Nasdaq 7924
Russell 1717
