We know that younger drivers are more likely to get in accident than drivers in their forties. This probably is due to a combination of factors -- a lack of experience plays a role, but also teenagers tend to process situations and evaluate risk differently than their older counterparts.

Is the same true for investing? Money's Jason Zweig looks at the ways that senior citizens are likely to differ from younger investors: "New research by finance professor Alok Kumar shows that the average investor exhibits an 'abrupt and significant drop in performance around the age of 70,' probably because of fading memory and rising impulsiveness."

It turns out that older investors may actually be less risk-averse, and more willing to gamble, than their younger counterparts. Combine this with the tendency for memory problems and less agile mental processing in the later years, and you have a group of people who are extremely vulnerable to hucksters and charlatans selling life insurance, stocks, or business opportunities.

In a move to make it one of the largest retail brokerage operations in the country, banking giant Wachovia (NYSE: WB) has bought AG Edwards (NYSE: AGE). The combined operations will become second only to Merrill Lynch (NYSE:MER), and ahead of Citigroup's Smith Barney. The new operation should have about 15,000 brokers.

It is easy to say that the move is simply a cost consolidation play. Wachovia says that it can take out [subscription required] about $400 million in duplicate costs, which should add to the profitability of the acquired assets.

Wachovia, however, is cleverer than simply making the purchase as a simple earnings play. Retail brokers are huge collectors of assets. The new, combined operation will manage $1.1 trillion.

Rival banks, including Bank of America (NYSE: BAC) and JP Morgan (NYSE: JPM) do not have networks of brokers anywhere near this scale. That gives Wachovia an edge in wealth and asset management that Citigroup already has. While Wachovia's stock is flat over the last year, Citi is up about 12% and JP Morgan has climbed well over 20%.

Perhaps Wachovia needs a little edge.

Stock futures point to a high open as U.S. stocks look as if they're going to continue yesterday's late-day rally when the S&P 500 closed at a record close. Investors will have a lot to chew on today as not only another big acquisition in the financial sector is making headlines, but a wave of economic data is to be released.

Yesterday, investors were concerned from a possible global sell-off as Chinese stock markets plunged 6.5%, causing declines in international markets. U.S. markets started the day on a down note, but then got a boost after minutes from the last Federal Reserve meeting regarding interest-rate policy were released. The minutes said the economy appeared to recover from its first quarter's sluggish pace. Consequently, markets closed higher with the S&P 500 setting a new record.

Today, there's a wave of economic data:

• At 8:30 a.m. EDT, the Commerce Department will release its revision for first-quarter GDP. Economists predict that GDP growth in the quarter will be revised down to 0.8% from 1.3% estimated in April.
• At the same time weekly jobless claims will be released, a pre-cursor for tomorrow's employment data.
• A little after markets open the Chicago Purchasing Managers will release its May manufacturing index. Economists predict the Chicago PMI to have risen to 54.0 in May from 52.9 in April.
• At 10:00 a.m., the Commerce Department will also report on April construction spending, which is expected to have slipped 0.1% after rising 0.2% in March.

Of course, the reports could impact trading today. Indications of too slow a growth would be bad for corporate profits, but may entice the Fed into a rate cut later this year. Indications of fast growth may indicated inflation could remain a risk and prevent the Fed from dropping rates. So far it seemed the market recently reacted more to possible rate cut moves than to possible slowing growth.

The rally in U.S. stocks affected global markets. Chinese stocks rebounded after plunging the day before, Asian markets closed mostly higher and European stocks also rallied, sending the Dow Jones Stoxx 600 Index to the highest since September 2000.
