Nautilus Investment Research recently said stock prices tend to soar whenever bitcoin experiences explosive growth. Bitcoin’s price has trended upward about 80% this last month. The S&P 500 has seen monumental increases in lockstep with bitcoin. It appears that bitcoin prices are correlated with rise in stock prices. 

The Business Insider article said, “These kinds of astronomical gains in bitcoin, it turns out, are correlated with a strong showing by stocks too, according to Nautilus Investment Research.”

For instance, if a company integrated Bitcoin in Japan, they would see their stocks soar.

Kevin Helms, writing for covered this phenomenon back in June. He said, “Small exchange-listed companies that have started incorporating bitcoin into their businesses are seeing a similar pattern in their share prices. A well-known Japanese day trader, Naoki Murakami, said that ‘All of these gains coincide with bitcoin’s rally,’ Bloomberg reported on Monday.”

It is unlikely, however, the same effect is occurring...
