Don’t Trust Inside Tips
This proverb warns against acting on tips from so-called “insiders” or “connected players” — what you might call “hot tips” or “whisper information.”
On social media, you’ll constantly encounter people saying things like “buy X and you’re guaranteed to profit” or “only idiots aren’t buying this stock.” These people are called “hype merchants” (煽り屋), and some of them are genuine market manipulators.
Why do they hype specific stocks? Simple — they’re doing it to profit themselves. The typical scheme: they quietly buy large amounts of a stock cheaply in advance, hype it to attract followers and beginners who drive the price up, then sell into that artificial demand.
Those who bought at the top end up holding large losses — sometimes career-ending ones.
Following this proverb, the safest path is to ignore all hype merchants and market manipulators, develop your own investment approach, and stick to it.
Hearing Early, Losing Early
“Hearing early” (早耳, hayamimi) refers to getting market-moving information ahead of others. Experienced investors often work hard to gather information faster than the competition.
But information that arrives very early is often inaccurate (rumor or disinformation), or — even if accurate — may not actually have a large impact on prices.
So acting on early-stage information too eagerly often leads to big losses, which is the lesson this proverb conveys.
Being first to information can be an advantage, but what matters more is the ability to accurately assess whether the information is correct and how significant its impact will truly be.
Charts Are the Trader’s Walking Stick
The “charts” (罫線, keisen) in this proverb refer to stock price history plotted graphically — what we call “stock charts.” The most common type is the candlestick chart; others include bar charts and line charts.
This saying originated with Masajiro Tazuki, a renowned late-19th-century Japanese trader. The meaning: stock charts are the trader’s walking stick (guiding tool) — they are the key reference for determining the direction of a trade.
The reason: markets often repeat patterns similar to the past, and historical highs and lows serve as important reference levels for future price movement.
This may seem obvious, but in practice many traders jump on news without ever looking at a chart, or buy stocks simply because they’re going up. This proverb advises: before anything else, look at the chart.
That said, don’t rely on charts alone. Use them as a “walking stick” — a guiding reference — while also incorporating other factors and your own market experience to make the final call.
Don’t Trade on Short-Term Views
This proverb says exactly what it sounds like: chasing small, short-term gains leads to nothing substantial, and often to losses in the end.
Once investors start winning with small, short-term trades, they get hooked and keep repeating the same approach — until eventually it fails and they lose big.
In the market, ignoring small short-term gains and patiently targeting large long-term profits is ultimately the more profitable strategy.
The Market’s Jack-of-All-Trades, Master of None
This proverb is almost identical in meaning to “Don’t trade on short-term views.” Trying to profit from both the up and down sides with clever, nimble tricks results in only small gains at best — never large profits.
A trader who seems to cleverly profit from every move may look impressive, but those who made their fortune this way are virtually nonexistent in the markets.
This kind of seesaw-style trading rarely works long-term. Even temporary small wins tend to eventually reverse into losses.
The better approach: instead of trying to be clever about every little move, focus your energy on thoroughly researching stocks and themes with genuine large-profit potential — and invest in those.
The Fisherman Reads the Tide
Just as a fisherman reads the tide to find where fish are abundant, an investor must read the flow of the market to make sound trading decisions.
The clearest market flows are a full bull market where everything is rising, and a full panic selloff where everything is crashing. In those environments, decisions are relatively straightforward.
But subtler flows matter too — specifically, which sectors are attracting capital right now. Just as there was a “game stock bubble” in Japan when smartphone social games were booming, the 2023–2024 period saw an “AI bubble” with AI-related stocks broadly rising.
Reading which types of stocks are attracting capital — from price momentum, trading volume, and other signals — and positioning yourself there is exactly what “the fisherman reads the tide” is all about.
When All the Bad News Is Out, It’s Time to Buy
“All the news priced in” (材料出尽くし, zairyō de tsukushi) means a state where all market-moving factors have already been reflected in the price and the stock barely moves anymore.
“All the bad news out” (悪材料出尽くし) means all negative factors have been fully absorbed into the current price.
When the downside factors are fully priced in, there’s little reason for the stock to fall further. This typically triggers buying — many investors simultaneously conclude it’s a buy, and the stock can suddenly rally. This phenomenon happens regularly in markets.
So, as the proverb suggests: when bad news is fully absorbed and the stock appears to have no more downside, buying may be the right move.
That said, it’s extremely hard to verify whether bad news is truly “all out.” Further negative news may emerge and push prices lower; prices may simply stagnate with no recovery.
Even harder: if a negative catalyst is widely anticipated, the market may have already priced it in before official confirmation — so when the bad news actually hits, nothing happens, or the stock even rises. Conversely, if a strong quarter is widely anticipated and priced in, an actually good quarter may trigger a selloff.
Whether news is truly priced in requires deep research into charts and investor psychology — it is never a simple judgment.
