The stock market halted its slide of the past three sessions today with a mixed showing marked by modest gains in some blue chip issues.

The Dow Jones average of 30 industrials, which had fallen more than 22 points in the last three trading days to a two-year low, recovered 3.47 to 821.64.

That New York Stock Exchange's composite index edged up .02 to 51.24. Butlosers held a slight edge on gainers in the daily tally on the Big Board.

NYSE volume totalled 20.41 million shares, down from 23.87 million in the previous session.

Nationwide turnover in NYSE-listed issues, including trades in those stocks on regional exchanges and in the over-the-counter market, came to 23.34 million shares.

Analysts said there was little in the day's news to relieve the interest-rate worries that have plagued the market of late.

At the close on Thursday the Federal Reserve reported a$4.9 billion jump in the basic measure of the money supply.

The news was taken as a signal that the Fed was likely to tighten credit further in its effort to combat inflation by restraining monetary growth.

But some buyers appeared anyway, apparently going on the theory that the market had taken the current negative news into account in advance with its recent slide. The surge in the money supply had been widely forecast.

Brokers said some traders who had sold short previously also seemed to be buying back in to cover their positions and nail down profits.

Standard & Poor's index of 400 industrials rose 111 to 102.07 and S&P's 500-stock compostie index added 10 to 93.56.

The Amex market value index dipped .02 to 115.57.

In the over-the-counter market, the NASDAQ composite index managed a .02 advance to 99.05.
