Long-term mutual funds saw net inflows for the 13th week in a row as the pace into stock funds increased from the previous three weeks, according to figures released Wednesday from the Investment Company Institute.

Total estimated inflows were $12.48 billion in the week ended June 10, bringing the total inflows for the past 13 weeks to almost $140 billion.

Stock funds had estimated inflows of $5.04 billion, up from $4.66 billion the previous week. Weekly outflows from equity funds topped $10 billion earlier this year before the market started to rebound in March, boosting traders' confidence that the end of the bear market might be in sight.

Inflows were $2.03 billion at U.S. stock funds, also marking their 13th consecutive week of inflows, while foreign funds took in $3.01 billion.

Meanwhile, bond funds saw inflows of $6.92 billion, down from $8.46 billion the previous week. Taxable funds took in $5.46 billion, while municipal ones got $1.46 billion.

Investors put $518 million into hybrid funds, compared with $533 million the previous week, the institute said. Such funds can invest in both stocks and fixed-income assets.

Separately, assets in money-market funds plunged $62.9 billion in the latest week amid especially steep withdrawals by institutional investors, according to iMoneyNet's Money Fund Report.

The weekly outflows mark the highest level since September when $120 billion was withdrawn from money-market funds in a single week amid the fallout from the Reserve Primary Fund "breaking the buck."

Meanwhile, the seven-day yield on taxable money-market funds continued dropping, to 0.13% from 0.15%. The yield has been steadily declining in the wake of a decision by the U.S. Federal Reserve Board to keep the target federal-funds rate under 0.25%, which was recently affirmed.

For the week ended Tuesday, total assets in money-market funds decreased to $3.632 trillion.

Overall taxable fund assets declined $60.04 billion to $3.169 trillion as institutional investors took out $53.7 billion and individual investors withdrew $6.37 billion.
