Jim Cramer is a proud American, loyal to making money on domestic shores. He knows when to stay out of Switzerland's debacle, ironically caused by the very country that is infamous for its no-interference policy.
Thus the "Mad Money" host warned investors that it is time to isolate themselves. Not in the kind of way that means locking yourself in your house and building a moat. He means keeping your eye open for opportunity, as the potential for making money is greater in the U.S. than overseas.
On Thursday, Switzerland opted to strengthen the Swiss franc versus the euro. It was a strategic decision aimed to keep funds flowing out of euro-denominated banks and into Swiss-franc denominated banks.
The move stunned currency traders worldwide, as it caused worries that the Swiss franc became too strong too quickly and could lead to the inability for Swiss banks to pay companies back.
"We are doing really well in this country, and these other places are just floundering around doing a whole lot of nothing," he added.
Don't just run out and gobble up all American stocks, Cramer warned. Be strategic and pick the domestic companies that can benefit investors on weakness.
