Analysis of the Reasons for the Limit-Up and Subsequent Trend of Fasten (000890)

Fasten (000890) hit the limit-up on December 11, driven mainly by two factors: first, the overall strength of the optical fiber and cable concept sector [3], with multiple stocks in the sector such as Tongguang Cable and Han Cable shares hitting the limit-up simultaneously; second, on the capital side, super large orders pushed up the price in the late trading on December 10 [2], and today’s Dragon and Tiger List shows that hot money net bought 42.2258 million yuan [1]. Technically, the stock has risen 16.85% in 30 days [0], today’s closing price of 5.34 yuan hit a 30-day high, with a turnover rate of 13.60% and a turnover of 292 million yuan, which is higher than the average daily trading volume of 173.5 million yuan [1][0].

1. Sector Linkage: The collective limit-up of the optical fiber and cable sector reflects the market’s short-term expectation improvement for the industry
2. Hot Money Dominance: The net buying of hot money on the Dragon and Tiger List and the push from late trading large orders indicate active short-term speculative funds
3. Technical Divergence: The price hit a new high while RSI is overbought, forming a divergence, and KDJ is in the bullish zone [0]
4. Valuation Hidden Danger: The negative profit valuation with P/E-25.65 and P/B-404.13 shows weak fundamental support [0]

• RSI overbought signal [0], with relatively large short-term correction pressure
• Negative profit valuation lacks fundamental support
• The market dominated by hot money may fluctuate violently

• If the sector market continues, it may further break through the resistance level of 5.47 yuan [0]
• High turnover rate indicates high market attention and sufficient liquidity

The limit-up of Fasten is driven by both the sector’s strength and hot money. Currently, there are overbought signals on the technical side and insufficient fundamental support. Investors need to pay attention to the breakthrough of the 5.47 yuan resistance level and the 4.58 yuan support level [0], and be cautious of short-term correction risks.
