[트레이더김씨] 2025년 9월 30일 화요일 (9월 마무리 매매리뷰/잡담/소통)

Summary

Trader Kim reviewed his September 2025 trades and answered questions about day trading, swing trading, risk controls, and adapting to changing Korean market conditions. The captions are machine-generated, so some company names and figures may be inaccurate.

September trading review and market context

• He said trading had become more difficult since the launch of NXT, particularly for breakouts and early-session moves. Some stocks now move several percent within seconds, making entries harder.
• He discussed rotating into shipbuilding as money appeared to move away from semiconductors. He cited buying about KRW 1 billion of a shipbuilding-related stock and selling around KRW 30,000 for a stated gain of roughly 19%. The exact stock and figures are unclear in the captions.
• He said the market was weak on the day of the stream, shortly before Chuseok, and noted that the index had risen substantially.
• In his September review, he discussed trading Robotis and other robotics stocks, including Rainbow Robotics and One Holdings. He also mentioned NAVER, DND Pharmatech, Ildong Pharmaceutical, NHN, and CP System. He said he missed a move in DND Pharmatech while filming, traded it later, and had a losing trade followed by an attempt to recover part of the loss.
• He gave examples of large position sizes: around KRW 1 billion in some trades, roughly KRW 3 billion in a Rainbow Robotics trade, and—during especially favorable markets—up to about KRW 10 billion in SK Hynix. He also mentioned past positions of roughly KRW 5–6 billion in NAVER or Kakao. He said he tries not to trade at a size that materially moves the ask.
• He claimed to have had no losing calendar year since beginning to trade, though monthly results varied. This is his personal performance claim and has not been independently verified.

Trading framework and risk management

• Choose stocks with market interest and potential volatility. Look for stocks the market wants rather than relying only on personal judgment.
• Identify leadership through price action. A stock’s leadership may become clear only after it starts moving, and apparent leaders can fail.
• Monitor several information sources. These include real-time searches, trading activity, percentage movers, news, and program flows. He said program activity matters when managing larger positions and that he generally watches whether programs are buying or selling without interpreting the activity in great detail.
• Use multiple chart timeframes. He said he watches 1-minute, 3-minute, and 10-minute charts, along with the broader market and daily charts.
• Keep breakout trades compact and cut failed setups. If a breakout does not follow through, exit rather than wait for a complicated signal. He described stop-loss decisions as largely experience-based.
• Limit losses relative to recent gains. He said he generally tries to keep a loss from exceeding about two or three days’ worth of profits. If losses begin to compound, stop trading.
• Control position size and avoid leverage. He warned that margin can magnify drawdowns and force liquidation before a stock recovers. He advised keeping exposure modest, avoiding positions that reach 20–30% of the account, and keeping it under about 10%.
• Avoid unplanned averaging down. If averaging down, define the maximum position in advance and keep additions small. Otherwise, cut the trade and consider re-entering at a better level.
• Stop after a strong session and take breaks after drawdowns. He said he often stops when profits are substantial and tends to rest when his account retreats from a peak, rather than trying to win losses back immediately.
• Adapt to market cycles. Strategies that work in one market regime may stop working and later return. He advised changing tactics to fit current conditions rather than relying blindly on any one method.
• Base swing trades on a company thesis. He said a swing position should reflect a view of the company’s value and resilience, rather than being a day trade that has turned into a hold.
• He said he separates accounts for closing-price trades, breakouts, and futures, and uses futures mainly around events.

Performance, costs, and cautions

• He said 20–30% monthly returns had been possible for him when his capital was smaller, and described consistently achieving such returns as strong performance. This was a personal anecdote, not a forecast or promise.
• He cautioned that frequent trading is costly: fees and taxes can steadily erode an account, especially with breakout strategies.
• He warned against chasing news, FOMO, revenge trading, oversized “high-conviction” bets, and repeatedly trading setups that do not suit the trader.
• For beginners, he recommended starting small, avoiding margin, and focusing on one or a few methods they can execute well. If possible, he advised keeping a job rather than relying on day trading for living expenses. He cautioned that bull-market gains may not persist and can be lost in a downturn.

Tickers, assets, sectors, and instruments mentioned

• Companies and stocks: SK Hynix, Samsung Electronics, Hanmi Semiconductor, NAVER, Kakao, Robotis, Rainbow Robotics, DND Pharmatech, Ildong Pharmaceutical, NHN, HJ Heavy Industries, Sejin Heavy Industries, Doosan Enerbility, Kolon Mobility, Osung Advanced Materials, Protina, Erkos (described as a SPAC-merger stock), and Dongyang Steel Pipe.

• Instruments and markets: Korean equities, U.S. stocks, Bitcoin, futures, and the Korean NXT trading venue.

Disclosures and sources
