NVIDIA Corporation (NVDA) stock analysis, October 8, 2026: NVDA tests $231 support after giving back all of its October gains

Published October 8, 2026 · NVDA chart, levels and live analysis

Key Updates

Executive Summary: NVIDIA shares fell -2.69% intraday and are down -2.53% since the October 7 report, declining from $237.10 to $231.09. The pullback erases most of the gains accumulated between September 28 and October 6, returning the stock to levels last seen in late September, despite the absence of negative company-specific news. The primary fundamental catalyst remains the record $150 billion buyback announced on September 29, which continues to underscore management's view that shares are undervalued relative to forward growth expectations.

The stock has now oscillated in a tight band over the past two weeks: +2.35% (Sep 28→Oct 2), +2.19% (Oct 2→Oct 6), -2.08% (Oct 6→Oct 7), and -2.53% (Oct 7→Oct 8). This pattern indicates a consolidation phase following the sharp run-up, with no single negative catalyst identified in the available news flow to explain today's decline, suggesting profit-taking or broader risk-off sentiment in AI/semiconductor names rather than a thesis-altering development.

Current Trend

NVDA remains firmly positive on a YTD basis at +23.91% and +26.92% over six months, confirming the structural uptrend remains intact despite near-term volatility. However, the 1-day decline of -2.69% versus a flat 5-day return (+0.10%) signals that recent gains have been fully unwound, with the stock now testing support near the $231 level — consistent with the September 28 close of $231.51. Resistance is defined by the October 6 high of $242.14. A break below $231 support could expose the stock to further downside toward the $225 region not yet tested in this cycle, while reclaiming $237-$242 would restore the short-term bullish structure.

Investment Thesis

The core investment thesis for NVIDIA rests on its dominant position in AI accelerator supply, sustained hyperscaler capital expenditure, and a valuation that — per CNBC — remains attractive relative to forecasted earnings growth. The company's fiscal 2028 forward P/E of 14.5x is well below its five-year average of 62.9x, and management is reinforcing this valuation gap through aggressive capital return, including the newly authorized $150 billion buyback atop an $80 billion May authorization, with plans to return roughly half of free cash flow to shareholders.

Thesis Status

The thesis remains intact and arguably strengthened on a fundamental basis following the buyback announcement, which signals management conviction despite macro-driven share price volatility. However, the magnitude and persistence of short-term price swings (four consecutive moves of over 2% in either direction) indicate the market remains highly sensitive to sentiment shifts around AI capex and semiconductor demand, even absent company-specific negative catalysts. The disconnect between strong fundamental signals (buyback, low forward valuation) and today's decline warrants monitoring for emerging risk factors not yet reflected in available news.

Key Drivers

The dominant driver remains the record $150 billion buyback program announced September 29, which continues to be referenced as evidence of an attractive valuation entry point, with analysts forecasting 60% net income growth and 70% sales growth for fiscal 2028. No new company-specific negative developments were identified in the available news flow to explain the -2.69% single-day decline, suggesting the move is likely attributable to broader market or sector-wide dynamics not captured in the provided sources.

Technical Analysis

NVDA trades at $231.09, down sharply on the day and testing support at the $231 level established on September 28. The stock has given back the entirety of its October 2–October 6 rally (+2.35% and +2.19% respectively), confirming a short-term reversal pattern within a broader YTD uptrend of +23.91%. Resistance sits at the October 6 high of $242.14. The alternating pattern of 2%+ daily/multi-day swings over the past two weeks points to elevated volatility and indecision, with the next directional confirmation likely to come from a decisive break of either the $231 support or $237-$242 resistance zone.
