If you're a shareholder of Delta Airlines (NYSE:DAL), you know it's been a rough couple of years. After trading around $50 per share just five years ago, the stock is down to less than $4 today.

But I'm here to tell you that one stock market loser isn't the end of your financial future -- so long as you have a plan and stick to it. Without a plan, stock market losers can wreak financial havoc on your savings and retirement.

Get one step ahead
The stock market is full of disasters. From the Great Depression to the tech bubble, investors in every era have experienced the pain of financial loss. But even those who have been most hurt can get started on a plan to rebuild their savings and investments and achieve their retirement dreams.

Despite any experiences with the UTStarcom's (NASDAQ:UTSI) (down 75% over the past year) and Magnetek's (NYSE:MAG) (down 71%) of the world, you are the best person to manage your money. By identifying an investment timeline, determining ideal asset allocation, and preventing fees, commissions, and taxes from undermining your future, you can get closer to achieving financial security.

Be one with the masters
Even the world's greatest investors are unable to predict the future. Jack Bogle, founder of the hugely successful Vanguard Group, told Fool co-founder David Gardner, "I am a nervous investor. Nobody knows what will happen tomorrow or next year. ... But [with] four things -- diversification, tax efficiency, lower costs, a long time horizon -- you will capture the returns that this uncertain stock market is kind enough to deliver."
