# 8/19 US stock analysis

A significant shift occurred in the market today as the U.S. Treasury announced an expansion of its long-term repo repurchase operations, at least doubling the maximum size of liquidity support repos. Following the announcement, U.S. Treasury yields retreated noticeably; the 10-year yield dipped to around 4.65%, while the 30-year yield also saw a clear decline. Pressure in the bond market eased somewhat, improving risk appetite and sparking a rebound in U.S. equity futures.

This news is considered short-term bullish for today's market.

In recent days, Treasury yields surged rapidly, with the 30-year yield hitting levels not seen since 2007. The sharp rise in long-end rates had placed considerable pressure on tech stock valuations. Today, after the Treasury signaled liquidity support, long-end yields pulled back, providing some support to high-valuation tech stocks.

However, it is important to note that

Although the bond market has seen some repair today, both the 10-year and 30-year yields remain relatively high. Meanwhile, crude oil prices and geopolitical tensions remain key risk factors. Therefore, today's rally should be viewed more as a technical correction rather than the start of a new unilateral uptrend.

I expect the broader index to gap up significantly, consolidate briefly, then push higher before pulling back.

Key intraday focus: Can the index continue to break out with increased volume after the gap up? If the rally fails to see a significant volume surge and the tech sector fails to strengthen synchronously, the post-gap-up spike may well become today's selling opportunity.

Subsequently, the broader index will likely drift lower, gradually filling the gap left by today's open.

Based on the current market structure, a gap-up-and-fade intraday pattern is more likely today.

Volatility is expected to be wide, with an estimated intraday range of 65 to 75 points.

SPX Today High: 7734

Extreme High: 7747

SPX Today Low: 7688

Extreme Low: 7663

Key Market Observations Today

First

Can the 10-year Treasury yield continue to fall?

If the 10-year yield continues to drop, it will support valuations for tech and growth stocks.

If yields resume their rapid ascent intraday, the probability of a pullback after the equity gap up increases significantly.

Second

Observe whether there is a volume-backed breakout after the gap up.

If the index spikes but volume does not follow through, and Nasdaq/semiconductors underperform the S&P 500, be wary of a fade.

Third

Watch the gap up.

If the gap up is large, any intraday pullback will make the gap a key price target.

If the index continues to drift lower and breaks support near the opening price, the probability of filling the gap increases further.

Fourth

Watch 7688.

7688 is a critical short-term support level today.

If the price pulls back to 7688 and finds support with a clear bounce, it indicates bulls still have buying capacity.

If 7688 is effectively broken, watch 7663 next.

Trading Strategy for Today

Do not chase longs simply because futures are rising.

After the gap up, observe market strength first, focusing on performance after the initial spike.

If the index meets resistance near 7734 and the tech sector weakens synchronously, consider fading the rally (shorting).

If 7734 is broken and 7747 is firmly held, the expectation of a gap-up-and-fade should be temporarily lowered, and short positions must strictly manage risk.

If the index drops sharply to 7688, do not chase shorts immediately; wait for a relief rally confirmation before acting.

Today is a high-volatility trading day. Position sizing is crucial; avoid heavy positions in short-term trades.

Key Operational Notes for Today

First

Do not chase longs on the gap up.

Second

Beware of a fade if the rally lacks volume.

Third

7734 is today's primary resistance level.

Fourth

7747 is today's extreme resistance level.

Fifth

7688 is today's primary support level.

Sixth

7663 is today's extreme support level.

Seventh

If Treasury yields resume a rapid rise, reduce long positions.

Eighth

If gold and Treasuries strengthen simultaneously while U.S. tech stocks weaken, be alert to a shift in market risk appetite.

Ninth

With wide volatility today, wait for a bounce to confirm resistance before shorting; do not chase shorts at lows.

Overall

The Treasury's expansion of repo operations provides liquidity support to the bond market, causing Treasury yields to fall and offering some support to U.S. equity futures.

However, following recent high-level consolidation, the broader index remains in a high zone. Today's rise is driven more by technical repair from easing bond market pressures.

Therefore, the key risk today is profit-taking after the gap up.

Watch the gap up.

Watch the spike.

Watch for resistance.

Watch the pullback.

Watch for gap fill.

Today is likely to see a gap-up-and-fade intraday pattern. A technical relief rally is expected late in the session, with the daily candle likely closing with a longer upper shadow.
