📅 On the calendar — and why it matters here

  • Fri Aug 21 — FOMC (Fed rate decision / minutes). the single biggest scheduled market mover — a rate surprise in either direction repriced everything, hardest on rate-sensitive names (growth, REITs, utilities, homebuilders). Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
  • Wed Aug 26 — GDP. the broadest growth read — confirms or breaks the soft-landing thesis. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
  • Wed Aug 26 — PCE inflation (the Fed's gauge). a hot print pushes rate-cut odds out (pressuring long-duration assets); a soft print does the reverse — one of the highest-impact releases. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
  • Tue Sep 1 — JOLTS (job openings). labor-market tightness — a cooling read eases wage-inflation fears. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
  • Fri Sep 4 — Jobs report (payrolls + unemployment). sets the growth-vs-recession narrative — a weak number lifts recession odds (hits cyclicals, consumer, financials); a strong one can paradoxically pressure rates. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.

What to watch next

  • The oncology theme's risk score decreased by 6 points to 44/100 (Elevated) this week. A lower risk score suggests a perceived reduction in volatility or uncertainty for the sector, which could influence investor appetite for these stocks. [SAVNG data]
  • The median price-to-model-value across 58 oncology stocks is 1.02x. This metric indicates how current market prices compare to intrinsic value models; a value close to 1.00x suggests stocks are trading near their estimated fair value, which can inform future price movements. [SAVNG data]
  • The 10-year Treasury yield is 4.65%, and the high-yield credit spread is 2.75%. Higher interest rates and credit spreads can increase the cost of capital for oncology companies, many of which are in development stages and rely on financing, potentially impacting their ability to fund research and operations. [macro data]
  • The VIX is at 15.42. A VIX reading in this range indicates moderate market volatility. Lower volatility can create a more stable environment for biotech and oncology stocks, which are often sensitive to broader market sentiment. [macro data]
  • The Shiller CAPE ratio is 41.79, and market risk is 44/100. These metrics provide a long-term valuation perspective and overall market risk assessment. A higher CAPE ratio suggests that the broader market is richly valued, which could imply a more cautious environment for all equities, including oncology stocks, if a correction were to occur.
