NEW YORK (
TheStreet) -- Investors need to believe in something and show the confidence to stick with those beliefs no matter how the markets may gyrate, Jim Cramer said on the
"Mad Money" on Monday.
He said investors must have conviction and then outlined a few long-term trends that investors should cling to for the next several years.
Cramer said he always values flexibility and bring opportunistic in with stocks, but without a world view, a long-term picture of the world, it's just too easy for investors to get shaken out when the next big market correction is upon us. That's why these long-term themes are so important. Investors can use them for years to come.
Theme No. 1: the Global Food Shortage
Cramer said the world's insatiable need for more and better food is not going away anytime soon. Whether it's producing enough grains to feed the world or keeping up with the world's rising middle class that's clamoring for more chicken and steak, it's pretty clear that farming is going to be good business for awhile.
Cramer said the formula for playing the global food shortage is an easy one. Food prices are up, farmers have more money. When farmers have more money, the buy more equipment and plant more seeds. That means stocks like

Action Alerts PLUS
. and fertilizer giant
are perfect stock picks for the long haul.
