Theta Decay
An option loses something valuable as the calendar moves forward: time. Theta estimates how much of the option’s value may disappear each day if other factors remain unchanged. An option with theta of -0.05 may lose about $0.05 per share over one day from time decay alone. The effect usually becomes faster as expiry approaches, particularly for options close to the current market price. Theta works against option buyers but can benefit sellers who collect the option premium. Real prices will not follow theta exactly because the underlying asset, expected volatility, and interest rates may also move at the same time.
Thin
A thin market has relatively few active buyers, sellers, or orders. With less depth available, even a modest transaction can move the price sharply. Bid-offer spreads may widen, and the price shown on screen may cover only a small quantity. Thin conditions often appear in less popular assets, outside the busiest trading hours, or before holidays and major announcements. The word describes liquidity, not whether the market is expensive or cheap. A market can be thin while moving higher, lower, or nowhere at all. For large orders, the important issue is that there may not be enough quantity available at the best quoted price.
Thirty (30) YR
Thirty years is a long time for money to remain invested at a fixed rate. The US 30-year Treasury bond is designed for that horizon. It pays interest every six months and repays its face value when the 30 years end. Because its payments stretch far into the future, its market price can react strongly to changes in long-term interest-rate and inflation expectations. Traders often use “30 YR” as shorthand for the bond’s yield. A higher quoted yield normally comes with a lower bond price. The 30-year is also called the long bond and is followed by pension funds, insurers, and other long-term investors.
Three Black Crows
Three Black Crows is a bearish candlestick pattern made of three consecutive falling candles. It usually receives attention after a market has been rising. Each candle closes lower than the previous one, and the bodies are normally large enough to show steady selling rather than small random movement. Traders interpret the sequence as a possible shift from buying strength to selling pressure. The pattern becomes less meaningful when it appears after an extended decline because the market is already weak. Like other candlestick formations, it describes what happened across a few sessions. It does not prove that a longer fall must follow.
Three White Soldiers
A market has been falling, then three strong rising candles appear one after another. This formation is called Three White Soldiers. Each candle normally closes above the previous close and shows consistent buying across the session. The pattern can suggest that buyers are taking control after a decline or period of weakness. Very large candles may also mean the move has already travelled far, especially if they appear after prices have risen for some time. Traders often examine volume, nearby resistance, and the wider trend before giving the pattern more importance. The three candles are evidence of buying pressure, not a guarantee of a lasting recovery.
TIBOR
TIBOR stands for Tokyo Interbank Offered Rate. It is a reference rate based on submissions from selected banks about unsecured yen borrowing in Japan’s interbank market. Japanese Yen TIBOR is published for several periods, including one week and one, three, six, and twelve months. It differs from the overnight transaction-based TONA rate. There were previously two TIBOR families, but publication of Euroyen TIBOR permanently ended after 30 December 2024. Japanese Yen TIBOR is now the only TIBOR benchmark calculated and published by the JBA TIBOR Administration. Older contracts and charts should be checked to see which version they refer to.
