All the mistakes in the financial market are nothing more than the two words "greed" and "hastness".

將Leonard Esau Baum（倫納德·伊索·鮑姆）的Baum–Welch（鮑姆－韋爾奇算法模型）進行改進，擴展，分段微分化+股神Warren Edward Buffett 的傳統價值投資理論。

對Elias=Jerome來說，Leonard Esau Baum（倫納德·伊索·鮑姆）的Baum–Welch（鮑姆－韋爾奇算法模型）+股神Warren Edward Buffett 的傳統價值投資理論 就是金融市場上的MG42機關槍。特徵爲高速高效，具有類似“撕裂布匹”的槍聲，空頭稱之爲“奪命電鋸”，此外同時具備可靠性、耐用性、簡單化、容易操作以及成本低廉等特性。Elias=Jerome雖然是學理論物理和應用數學的。坦率地說，套戥平台Leonard Esau Baum（倫納德·伊索·鮑姆）的Baum–Welch（鮑姆－韋爾奇算法模型）中的有些東西，比如靜態參數，動態參數，泛函，非函等的計算和設置，沒有完全搞懂。似乎只有搞純數學的才能徹底弄懂，James Harris Simons已經公開說了那是他們核心機密，無可奉告。另外，Elias=Jerome對計算機軟件方面是很弱的，很多iOS軟件的使用都不知道，更別提編寫和架構軟件程序了。

The MG42 is characterized by its extremely high rate of fire, up to 1,500 rounds per minute. When firing, unlike other machine guns, it makes a sound similar to "tearing cloth". The Allies called it "Hitler's chainsaw". In addition, it also has the characteristics of reliability, durability, simplicity, easy operation and low cost.

The MG 42 (shortened from German: Maschinengewehr 42, or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II.

Designed to use the standard German fully-powered 7.92×57mm Mauser rifle round and to be cheaper and easier to manufacture, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges: it averaged about 1,200 rounds per minute, compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29, or Bren gun. This made it extremely effective in providing suppressive fire. Its unique sound led to it being nicknamed "Hitler's buzzsaw".

MG42的特點是射速極高，最高可達每分鐘1500發。射擊時，與其他機槍不同，它會發出類似於“撕布”的聲音。盟軍稱其爲“希特勒的電鋸”。此外，它還具有可靠、耐用、簡單、易操作和低成本的特點。

MG 42（德語縮寫：Maschinengewehr 42，即“機槍42”）是德國後坐式風冷通用機槍，在二戰後半期被德國國防軍和武裝黨衛隊廣泛使用。它於1942年開始生產，旨在補充和取代早期的MG 34，後者價格更昂貴，生產時間更長，但這兩種武器都生產到二戰結束。

MG 42 的設計目標是使用標準的德國全功率 7.92×57 毫米毛瑟步槍子彈，而且製造成本更低、更簡單，因此被證明非常可靠且易於操作。它最引人注目的是，對於使用全功率制式彈藥的槍來說，它的循環速率非常高：平均每分鐘約 1,200 發，而 MG 34 約爲 850 發，其他常見機槍（如 M1919 勃朗寧、FM 24/29 或布倫機槍）爲 450 至 600 發。這使得它在提供壓制火力方面非常有效。它獨特的聲音使它被暱稱爲“希特勒的圓鋸”。

Elias=Jerome只能另闢新徑，揚長避短，擴大容錯空間，有容乃大。根據實際參數情況進行有效地校驗，然後兩者巧妙地互相融合，定性分析與定量分析兼顧，相輔相成，相得益彰，有原則更有靈活才是王道和王牌。
