TOKYO -- With Japan's Golden Week holiday over and out, it's time to get back to basics. That means everyone in Tokyo will be doing what everyone in New York is doing -- trying to handicap whether the U.S. Federal Reserve will hike interest rates by 25 or 50 basis points at their mid-May meeting, and whether this hike will rock the already shaky Nasdaq Composite Index.

But for Tokyo traders, that's not all. More than 1,500 companies will be releasing their fiscal 1999 earnings over the next three weeks, no doubt taking the migraines and ulcers that went away during the long spring holiday out of remission.

Amid the earnings rush, many fund managers will be looking closely at the numbers for semiconductor companies, one sector in Japan that is expected to keep booming amid the global mobile phone bonanza. Leading liquid crystal display manufacturers such as

Matsushita Electric Industrial

(MC) - Get Report

,

Sharp

(SHCAY)

and

NEC

(NIPNY)

will be releasing their numbers starting Wednesday. Despite paltry profits -- or losses -- these LCD makers may post for the fiscal year ending March 31, their outlook for the following year is expected to be superb, as the demand for LCDs and other chips used in mobile phones outpaces existing supply.

Demand is not the only reason investors are looking at these stocks. All three are in the revamped

Nikkei 225

index, Matsushita having been added just a few weeks ago, which means it will be included in many of Japan's new mutual funds' portfolios.

Since the beginning of the year, mutual funds have been the main buyers of stocks in Japan, purchasing 1 trillion yen ($9.3 billion) worth of shares. That's more than double the total net purchases made during 1999. And even though recent market volatility has made some investors think twice before investing, Kathy Matsui, chief strategist at

Goldman Sachs

, says, "Japan's equity culture is just beginning to emerge among Japanese retail investors and their participation in the stock market is likely to increase over time."

Twelve new mutual funds will begin operations by the end of this month. Eight funds are targeting a mixture of growth and value stocks, two funds will pick up only technology shares, while the rest will dip into small-cap and other Asian shares, according to

Morningstar Japan

. So even if one conservatively estimates that half of these funds will pick up shares listed in the Nikkei 225 index, as well as the three chip makers, that's a whole lot of money heading into the market.

Listed below is a quick look at earnings estimates, stock price and recent movements for the three American depositary receipts.

Matsushita Electric Industrial

Group operating profit is estimated to fall 15% from the previous year, to 164 billion yen, with net profits jumping 600%, to 95 billion yen. Parent net profit is estimated at 43 billion yen, down 31% from the previous year.

Posted operating profit is expected to increase for the first time in nine quarters during the October-December quarter due to a rise in LCD sales.

Unlike its rival,

Sony

(SNE) - Get Report

, critics say the firm lacks a clear business strategy. However, the company has made headway in Europe, holding a 15% stake in

Open Interactive

, a U.K. firm that runs one of the most successful interactive television services in the world. It also holds a 9% stake in

Symbian

, a consortium whose software is one of the leading contenders to backup the third generation of mobile phones. These investments and their business strategies will likely be brought back to Japan.

ADRs are down 2% from the start of the year, last traded at 273 3/8.

NEC

Expects consolidated net loss of 10 billion yen for fiscal 1999, but estimates that profit will jump to 70 billion or 80 billion yen during fiscal 2000, which ends March 31, 2001.
