The stock market saw another opening rebound fizzle Tuesday as the 10-year Treasury yield surged toward 4%.

The S&P 500 index tumbled to a bear market low, but the major indexes rallied to close mixed.

Twitter stock rose 1.4% to 42.11 on Tuesday.

The 10-year Treasury yield rose 2 basis points to 3.98%.

The stock market once again tried to bounce near the open, with stronger, broader gains Tuesday morning than on Monday.

But as the 10-year Treasury yield soared to a fresh 12-year high, fueled by a number of stronger-than-expected economic reports at 10 a.m.

ET, the major indexes reversed lower, with the S&P 500 breaking below its June lows.

The Dow Jones Industrial Average fell 0.4% in Tuesday's stock market trading.

The 10-year Treasury yield leapt 9 basis points to 3.96%, hitting 3.99% intraday.

The 10-year yield hasn't topped 4% since April 2010.

The two-year Treasury yield is at 4.3%, edging lower on the session.

Vertex stock rose 2.9% to 284.74.

SWAV stock climbed modestly for a second straight session, up 2.4% to 260.83.

Tesla stock climbed 2.5% to 282.94 on Tuesday.

But as Treasury yields roared higher yet again, the major indexes pared, erased and reversed those gains.

The Nasdaq has not yet undercut its June bear market lows or even Friday's intraday.

The Cboe volatility index, or VIX, rose to a fresh three-month high, backing off intraday highs as stocks rallied late.

The bear market could be on the cusp of starting a new leg down.

It's hard to see the S&P 500 and overall stock market having a sustained rally with Treasury yields and the dollar soaring.

Perhaps the 10-year yield will hit resistance around the 4% level.

It's possible that the 10-year yield could top out earlier, but that would likely reflect expectations of a clear-cut U.S.

The last two days have shown the dangers of buying stocks during a strong open in a bear market.
